It looked like Kourtney Kardashian woke up on the wrong side of the bed in a new teaser (vấn đề hóc búa, vấn đề khó giải quyết) for Keeping Up With The Kardashians out on Tuesday.

On this lunchtime, I have some unfortunate news, the tired tradition of ‘getting up on the wrong side of the bed’ is a legitimate (xác thực, chính thống, có lý) psychological (tâm lý) thingo (biệt ngữ). According to a new study, those who wake up believing that today will screw (lừa đảo, lường gạt; làm tình, giao cấu) them will invariably be screwed by today.

Waking up on the wrong side of the bed is more than just an idiom. If sleep studies are to be considered, the shut-eye position and the side you choose to sleep on impacts (tác động tới) the quality of sleep (chất lượng giấc ngủ) and its subsequent (đến sau, xảy ra sau) benefits (lợi ích). Whether you pass out curled up (co tròn, thu mình) or straight on your back (nằm ngửa) can determine if you wake up feeling recharged (thư giãn/phục hồi sức khỏe) or drained out (tiêu hao, kiệt quệ).

He did, to everyone’s shock, wake up on the wrong side of the bed one morning in 1996 when he lost the Wimbledon quarter-final to the eventual champion, Richard Krajicek, who at the time boasted of one of the fastest serves in the game. Sampras recalled later in his book that it was also Krajicek’s backhand-return off his own serve that caught him off guard, and after three hard-fought sets played over two days, the defending champion made an exit.

I recently decided to remodel my bathroom (nhà vệ sinh, nhà tắm) myself (tự làm) instead of hiring a contractor (nhà thầu) to do it, which would have cost $65,000. I did it myself for $25,000 in materials and some hired help. It took up my weekends for nine months (mất trọn các ngày cuối tuần trong 9 tháng), time that I otherwise would have spent in advancing my career. I enjoy the hands-on work, but would I have been better off focusing on my job (tập trung công việc) and trying to earn more money (kiếm thêm tiền)? Was the bathroom worth it?

While it’s certainly more time-efficient (hiệu quả về thời gian) to hire (thuê) a contractor, and you could have used the time to further your career, it sounds like you got a lot of satisfaction (thỏa mãn) out of remodeling the bathroom yourself. Several colleagues and I conducted research a few year ago on what we called the “Ikea effect.” (hiệu ứng Ikea) It turns out that when we assemble something ourselves, we end up taking a lot of pride in it, and for a long time. So I wouldn’t just think about money and time. Think also about the pleasure of inviting friends to your home, showing them your bathroom and taking pride in your craftsmanship (sự khéo tay, lành nghề/thạo nghề).
